TACK-DRIVER.

SPEGIFICATION forming part of Letters Patent No. 744,282, dated November 17, 1903. Application filed September 11, 1902. Serial No. 122,917. (No modelJ T at whom it may concern.-

Be it known that I, STANISLAS BEAURE4 others skilled in the art to which it appe'rtains to make and use the same.

My invention relates to an improved tackdriver of that kind which isused in combination with lasting-tools for fixing the uppers of boots and shoes to the last. I

The objectof my invention is to provide a handy tool which is adapted to hold a large quantity of tacks and to enable them to be fed down regularly and uniformly one at .a

time as required when driven into place.

My invention consists, substantially, in providing a tack-holder having a plurality of parallel slots forming a species of grid the bars of which are open at one end, and 'the' tacks being placed in these slots in a row are caused to slide down the same one at a time by a ratchet-escapement. Further, Iprovide means for shifting the tack-holding plate so that the successive slots come alternately opposite the feed-slot of the machine, in which is located said ratchet-escapement, and I provide means for retaining thetacks in all the slots which have not yet come into use and been emptied.

My invention further consists in the con-z struction audcombination of parts hereinafter described,and more p'articularlyset forth 1 in the claims.

In the accompanying drawings I have shown the most approved form of myimproved tack-driver, and herein Figure 1 is a side elevation of my improved machine from the left side. Fig. 2 is a side elevation from the right side. Fig. 3 is a longitudinal central section through the head of the tool, showing the apparatus in position for driving a tack. Fig. 4 is a similar view to Fig. 3, showing the positions of the parts after the driving of the tack. Fig. 5 is a perspective view of one jaw of the lasting-tool. Fig. 6 is a similar view of the other jaw carjaw 10, as shown.

andiwhich have at their rear ends handlearms 12 13 and at their forward ends nose- .pieces 14 15, having serrated surfaces adapted to grip the leather of a shoe-upper in the ordinary manner. These jaws are pivoted together on a transverse pin 16. The upper side of the jaw 1O, whose head end is on the upper side of the tool, is flattened, as shown at 17, to form 'a guide-rest for the forward end of the oscillably-mounted tack-holder18,

which is clearly shown in Fig. 7 and is of rec tangular form, pivoted at its rearend upon a pin'l9, which secures it to a bracket-arm 20, bolted to the base of the handle 12 of the This tack-holder is slightly deeper or thicker than the length of the tacks, and it has formed therein a plurality of longitudinal parallel slots 21, so as to form the holder 18 after the manner of a grid open at its lower end and between the bars 22 Whereof are adapted to rest the tacks 23, supported by their heads and having their points depending through the slots 21, as shown.

. The forward end of the jaw 10 carries the tack-driving head 24, which has rising therefrom a cylindrical tube or casing 25, in which a reduced stem 27 on its lower end adapted to strike and drive a tack. This plunger 26 has on its upper end a head 28, provided with a cushion 29 to prevent injury to the hand or fist, and it is supported normally in its raised position by a compression-spring 30, coiled about the stem of the plunger and abutting against the lower side of the head 28 and the upper end of the tube 25, respectively. On the side of the plunger. is a groove 31, in which engages the stop-screw 32 in the side of the plunger casing, which is secured against coming out by a lock-nut 33. The lower end of the driving-head has a vertical tube 34, into which the tacks are adapted to successively drop, and it is of just sufiicient size to guide them steadily therein, the upper end of the tube being flared into a converging chamber 35, as shown. Communieating with this chamber is a longitudinal slot 36, which extends between the forward end of the tack-holder l8 and the chamber, so as to form a continuation of the slots 21 between the bars thereof and to carry the tacks located between said bars through the slot 36 successively. At the side of the slot 36 is located a toothed ratchet escapement-wheel 37, pivoted on a screw 38 and operated bya stationary and movable pawl,designated, respectively, 39 and 40, the latter being pivoted on an oscillating piece 41, loosely rotatable on the screw 38 and being of a resilient nature, so as to be held always in contact with the teeth. The pawl 39 is likewise of a resilient nature and is held in place by means of a screw 42, secured to the front of the tackdriving head. Connected with the piece 41 is a hand-bolt 43, which is pivoted thereto at 44 and has at its rear end a hook 45, adapted for the engagement of a finger of the hand holding the lasting-tool, while the other hand depresses the plunger 26. The rear end of the bolt 43 is guided by a bracket 46, and it is held in its projected position by a compression-spring 47, rest-ing, respectively, against the forward side of the bracket 46 and against the transverse pin 48, driven into the side of the bolt 43. The arrangement is such that when the bolt is pulled to the full extent of its movement the pawl 40 will cause the ratchet-wheel to be turned until one tooth thereof has passed the pawl 39, when the spring 47 will return the bolt to its original position. The turning of the ratchet escapement-wheel at the same time causes one tack to pass down the slot 36 and drop into the chamber 35, whence it falls into the tube 34 and is ready for driving. When, therefore, it is desired to drive a tack, it is only necessary for the hand holding the tool to pull the bolt 43 for an instant, thus setting the tack in position and immediately thereafterdepress the plunger 26.

The tack-holder 18 is provided with a coverplate 49, which is likewise pivoted upon the screw 19 and whose lower end is turned over at right angles, as shown at 50. It will be seen that the lower end of the tack-holder is made in the shape of a circular arc concentrio with its pivot, so that the ends of the slots 21 shall always form an immediate continuation with the slot 36 when opposite the latter. The angular flange 50 of the coverplate extends over the ends of all of the slots 21 when the machine is filled, and its lefthand edge is adapted to strike against the outer face 51 of that part of the head in which is formed the slot 36, so that the cover-plate cannot pass beyond this portion. In this position also the slot 36 will be covered by the tab or extension 52 on the lower corner of the plate 49, which covers said slot.

The operation of the instrument is as follows: It is first held in such a position that the upper surface of the tack-holder will be either level or slant backwardly, so that tacks may be readily placed in the slots,into which then will fall naturally with the head up and points downwardly of their own accord. When all the slots have been filled,the coverplate is turned on its pivot until the tackholder is completely covered,and the latter, with its cover-plate, is then turned about the same pivot until the first of the slots 21' that is to say, the left-handmost slot-comes opposite the slot 36 in the head of the tool. The tacks in this slot 21 will then slide down until the lowermost tack strikes the ratchetescapement 37, and the instrument will then be in position to drive tacks continuously until all the tacks in the said slot 21 have been exhausted, whereupon the tack-holder is turned slightly until the next slot 21 comes opposite the slot 36, and the same operation is repeated. As the tack-holder is turned the cover is held stationary and prevented from following, and this continues until the tacks in all the slots have been successively exhausted. The tack-holder is clamped in position during use by the screw 19, which fits in a threaded socket on the bracket 20, and thus enables the holder and cover to be jointly secured to the latter as firmly as may be desired.

I preferably form the chamber 35 open at its upper side, and the slot 36 is formed by two separate lug-pieces 53, which are of the form clearly shown in Fig. 8 and are secured to the sides of the driving-head by screws 54.

At 55 is shown a spring attached to two posts 56, embedded in the two opposite members l0 and 11 of the apparatus for holding them apart except when squeezed together to grasp the leather.

While I have shown in the accompanying drawings the preferred form of myinvention, it will be understood that I do not limit myself to the precise form shown, for many of the details may be changed in form or position without affecting the operativeness or utility of my invention, and I therefore reserve the right to make all such modifications as are included within the scope of the following claims or of mechanical equivalents to the structures set forth.
